People like to think that there is life on other planets. I think this is a fantesy. In my opinion, if there is no evidence it means there is no life. Let’s now look at the findingsof some of the explorations.
To begin with, in spite of the fact that Mars has an atmosphere, the environment of Mars seems unfriendly toward life as we know it on earth.
Moreover Mars is small, so there is not much gravity. For this reason, much of the atmosphere of Mars has drifted away. With little atmosphere, and no ozone layer, there is less protection from the ultraviolet radiation of the sun, which is very harmful to life. With little atmosphere, there is only a little pressure, which sophisticated life forms such as humans need to keep blood from boiling.
Scientists discovered in the past that liquid water flowed on the surface of Mars. With a liquid water habitat and a thicker atmosphere, life may have once prospered, still more exploration of Mars is needed to determine if life was once present there.
To conclude,I can say that I don’t belive that thare is life on other planets.We don’t have proof that this is true. When scientists have proof,then maybe I will belive it
